Title: Frequency division ratio setting data calculation system
Inventor: CHIKUI NAOHIKO
IPC: H03D7/00
Filed: 1993-11-30
Abstract: PURPOSE:To reduce a reception frequency setting time as a frequency division ratio by adding data in MHz digit for an intermediate frequency and a setting frequency stored through calculation in advance to data resulting from data in kHz or below in the setting frequency for each calculation. CONSTITUTION:A mixer 3 converts a reception frequency (fr) by using a frequency fr+IF outputted from a VCO 6 under the control of a PLL IC5 to provide an output of IF 4. Furthermore, a CPU 8 controls the IC 5 via a data output section 9 and applies each arithmetic operation to the data fr in kHz digit or below on each occasion. That is, the data fr are divided into data in MHxz digit and kHz digit (H and L), only the data frL are stored as data X and a quotient Y of X/M and a residue X' by using a frequency division value M of a prescaler are obtained through repetitive subtraction. Succeedingly a quotient (y) and a residue (x) of the data IF and frH calculated and stored in advance based on the Y, X' and in the case of A'>M (N' and A' are tentative setting values obtained thereat), correct setting values N, A are outputted from (N'+1) and (A'-M). Thus, number of arithmetic operations of the CPU 8 is considerably reduced and the setting time for the data fr is reduced to improve the scanning efficiency.

Title: Superpolishing method and slurry for it
Inventor: BURENTO RAN DEN HARUTOGU
IPC: G01Q60/00
Filed: 1994-12-27
Abstract: PURPOSE: To obtain a superpolishing method which polishes the surface of a disk substrate to the smoothness of an atom level. CONSTITUTION: This superpolishing method uses a chemical finishing treatment and a mechanical finishing treatment in combination. The surface of the disk substrate subjected to machining to prescribed surface roughness (namely, rough machining) is susceptible to erosion of an etching material. The substrate material is softened by the etching material in this slurry. The softened substrate material is thereafter wiped away and removed by the mechanical effect of the soft colloidal particles included in the slurry. As a result, the average surface roughness lower by one order than the disk surface subjected to the polishing treatment by the hard particles is attainable with the resulted disk substrate surface.
